IPC: H01L51/52
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To keep a multilayer structure in an airtight state over a long period of time, by forming a sealing film, by a plasma CVD method using silane gas and nitrogen gas, on the multilayer structure comprising a positive electrode, a plurality of organic compound layers, and a negative electrode, provided on a glass substrate. SOLUTION: A positive electrode 2 comprising a transparent electrode of ITO etc., is formed by deposition on a transparent glass substrate 1, and on this, a hole injection layer 3 of copper phthalocyanine etc., a hole transfer layer 4 of a triphenylamine derivative etc., a luminous layer 5 of an aluminum chelate complex etc., an electron injection layer 6 of LiO2 etc., and a negative electrode 7 of Al etc., are deposited in this order, to form a multilayer structure 8.

Inventor: KAWABATA HIKARI
IPC: B65B51/06
Filed: 1990-09-13
Abstract: PURPOSE:To make it possible to stick a label on a joint of packing paper even if the paper is thin by applying magnetic ink to the end of piled packaging paper, packaging an article in such a manner that the end comes to a joint, and detecting the end by means of a magnetic sensor. CONSTITUTION:Magnetic ink 4 containing metal powders such as iron powders is applied by means of a coating roller 6 to an end 2a of a plurality of packing papers 2 which are piled up. In this case, since a plurality of sheets of paper 2 are paled up, the ink 4 is not applied to a principal side of the paper 2 and hence value of the paper 2 is not reduced by the ink 4. An article 8 is packaged with said paper 2, in which the article 8 is packaged in such a manner that the end 2a of the paper 2 to which the ink 4 has been applied comes to a joint 3. By inspecting the end 2a by means of a magnetic sensor, the joint 3 of the packing paper can be detected. Consequently, even when the packing paper is thin, its joint 3 can be detected, A label 30 is applied to the joint 3 which has been detected.

Abstract: PURPOSE:To enable drying to be performed properly and evenly in every time the drying running is continued a plurality of times by turning off a heater and turning on only a blast mamas by both temperature sensors provided an inlet and outlet of a heat exchanging means if the starting temperature condition is judged insufficient. CONSTITUTION:In a prior clothing drier, the running thereof is started while a difference between T1, T2 is present, so that sufficient drying is not achieved. Thus, when at least a predetermined difference between temperatures T1, T2 is present in the start of running or temperature T1 or T2 is at least a predetermined one, a heater 11 is suspended until temperatures of an inlet and outlet 21, 22 of a heat exchanger are made equal to each other, and after blast running of running only a motor 12 both heater power control switch 7 and motor power control switch 8 are turned on to perform the normal drying running. Thus, even if another clothing is to be continuously dried a plurality of times, the condition for the starting point of running can be made equal to that for the first time.

Title: Petroleum burner
Inventor: KAWASAKI YOSHITAKA
IPC: F23D3/10
Filed: 1984-11-20
Abstract: PURPOSE:To make a rapid flame spreading from the lower part to the upper part by providing a narrowed part above a wick edge under a flat combustion chamber and equipping rows of air vents of a large diameter on the side wall of the combustion chamber. CONSTITUTION:The pressure controlling plate 19 is provided above the edge of the wick 11 beneath the combustion chamber 17 to form a narrowed part 20. On the side wall of the combustion chamber 16 above the neighborhood of the narrowed part 20, lines 15a of air vent with a diameter larger than that of downward air vents 15 are provided. Gasified fuel, air flowing in from the air vents 15 and combustion exhaust gas are lifted by the draft produced in the combustion chamber 16, but the lower part of the combustion chamber 16 makes a half-closed space by the pressure controlling plate 19, pressure acts laterally and flames are equalized in this space. The narrower the narrowed space is the more remarkable the flame equalizing effect is. But, the flames are hard to spread. Therefore, when rows of air vents 15 of large diameter are provided, a large quantity of air is made to flow in and mixture of the mixed gas with air is accelerated to make an inflammable state, flames are formed easily and stably. These flames make ignition sources and upward combustion progresses continuously.

The resultant tray 3 is put into a heating chamber, the temperature inside the chamber is kept at 20-35 deg.C, and the sheet 4 is constantly sprinkled with gibberellin-contg. water in a showerlike manner. The unpolished rice a then germinates, the length of the sprouts c reaches ca.10cm after 96hr, and the roots d are also grown. Thus, the objective unpolished rice sprouts of high nutritive value can be harvested in high yield in a short time.

Title: Multidomain liquid crystal cell and its production
Inventor: KIM JONG HYUN
IPC: G02B1/12
Filed: 1997-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain multidomain liquid crystal cells improved in visual field angle by forming orientation directions having pretilt angle varying in magnitude with respective domains. SOLUTION: The partial regions of substrates 31 coated with oriented films 32 consisting of photo high polymers are subjected to perpendicular photoirradiation in such a manner that translucent parts 33 of a mask exist therein. If the oriented films 32 are then subjected to inclined irradiation, the orientation directions on the irradiation direction side of the light among the degenerated orientation directions are selected. The upper and lower substrates 31 are produced by utilizing such properties and are stuck to each other.  As a result, the orientation directions of the respective domains of the respective substrates are the same but the magnitude of the pretilt angle varies and, therefore, the visual field angle on the side having the small pretilt angle are eventually affected by the side having the large pretilt angle opposite thereto and the directors of liquid crystals are eventually inclined in an opposite direction, by which the main visual field angle directions are made opposite to each other. As a result, the visual field angle is compensated between the adjacent domains, by which the visual field angle is improved.
